I have a class which must return a CGRect from one of its methods:

-(CGRect)myRect
{
    CGRect rect = CGRectMake(self.mySprite.position.x,self.mySprite.position.y,self.mySprite.textureRect.size.width, self.mySprite.textureRect.size.height);
    return rect;
}

I get an exc_bad_access as soon as i try to access the mySprite ivar.

Thing is if i call it, the instance variable mySprite is full of garbage. BUT if i change the function to return void, self.mySprite does contain the correct data.

-(void)myRect
{
    CGRect rect = CGRectMake(self.mySprite.position.x,self.mySprite.position.y,self.mySprite.textureRect.size.width, self.mySprite.textureRect.size.height);
    return rect;
}

that does not crash when accessing mySprite...
